Much of my research takes a phylogenetic approach to biological questions. I am especially interested in very large scale analyses and tools to automate the path from sequences to annotated trees in a reproducible way. The image is Darwin's first...

With Jenny Rock, Nia Whitely, and collaborators I have investigated the phylogeography and ecological adaptation to different water temperature environments in Gammarus duebeni . This species shows divergence between freshwater and marine forms (subspecies) and its enormous lattitudinal range has interesting...

In collaboration with Carlos Hasbun we studied the phylogenetics and genetic diversity of Mesoamerican spiny-tailed iguanas using both fresh samples and formalin preserved museum specimens. These revealed 3 major genetic groups that corresponded to the
Ctenosaura flavidorsalis,
C. quinquecarinata and the recently described
C. oaxaca species.

One of the most talked about ideas in genetic studies of asexual reproduction has been that of extreme Allelic Sequence Divergence (ASD), often called the "Meselson effect" after Matthew Meselson who is usually credited with this idea. In obligatory asexuals...
